Yeah , got my tTITO working

[AndyP]

hmm last response didnt work.

i trid the daisy chaining of rs232 and it did not appear to work. i daisy chained 3 machines together. and changed the sas address for those machines

anything that i transmitted from the pc was only recieved by the first gaming machine in the loop
likewise anything transmitted from machines, the pc only saw what was transmitted by the last machine in loop

i would actually like to explore the rs485 option though, i dont like the idea of all  machines going down if one is powered off.

You need to feed the tx through to rx and or machine TX. I think I posted an example schematic here somewhere that can be made on protoboard with jelly bean parts.

rs485 is still a good option. You could also make interface to the EGM with jelly bean parts on protoboard. In fact, here is some cheap stuff off ebay: http://www.ebay.com/itm/RS-232-RS-422-Communication-Data-Converter-Adapter-/270795858242?pt=AU_Components&hash=item3f0cb0e142

Does anyone know what this adapter is for
it's a WMS eithernet to DB9,
it uses pins 2-3-5-7 at the DB9 end, the pin 5 is ground
anyone know what that DB9 pinout is
I'm wondering if it's an adapter for the com port in a Bluebird

if you can tell us what the IC is and what pins of the IC that pins 2,3,7 of the DB9 go to we might be able to tell you whether you need a straight serial cable or null modem (crossover cable).

Pin       DTE or PC               DCE
2          Transmit Data  -->  Recieve Data   
3          Recieve Data  <--  Transmit Data
5          Ground         <->  Ground

Not sure about pin 7

It's hard to tell from the picture, but that looks more like a Ethernet 'cable' to DB9 converter than a Ethernet 'signal' to RS232 converter. There does not seem to be enough electronics on it to be a signal converter. Looks like there is just a MAX232 chip and one other (probably an opto-isolator).

If it's just a cable converter, it's probably pretty useless for a home environment since a standard RS232 cable would suffice. Despite the 'official' lengths for RS232, you can easily go several hundred feet if not more with no problem.

If it is a Ethernet signal converter (which I doubt), then you still may be SOL without the drivers for it.

Thanks for the responses

it has an i/c with 16 pins its marked

ICL
3232ECA
L548GBR

if the dot on the chip is pin 1 then
pin 11 goes to pin 2 of the DB9
pin 12 to pin 3
pin 15 to pin 5
and pin 7 of the DB9 comes up under the chip and I cant see what it goes to

I got this as a freebie from Johnny to many numbers, so I was just curious if it was good for anything

Thanks for your help

That is just a MAX232 equivalent. What does the other chip say?

[stayouttadabunker]

It appears to have small jack on the front right hand side of it too.
I imagine it needs to powered up with some voltage to make it work?
Is there a hanging 2-wire harness laying around in the machine that would fit it?

Looks like power that you would get from a wall wart.

[westec1]

The other chip is

MAX3080E
CSD 0508

And it does have a power input on it, and there is no power plug for this in my machine
it would use some sort of power adapter, probably 12v
I'm thinking its just an Ethernet to RS32 adapter.

[poppo]

The other chip is

MAX3080E

"The MAX3080–MAX3089 high-speed transceivers for RS-485/RS-422 communication contain one driver and
one receiver."

http://pdfserv.maxim-ic.com/en/ds/MAX3080-MAX3089.pdf

So, RS-485 over CAT5 to RS232

Most likely a 5v PS as the max VCC is 7V. Unless there is a voltage regulator somewhere on the board.

Thanks Poppo

I was wondering if it would be good for the SAS communication with my Bluebird,
now I know a lot more about it

I know that if you use a foreign JUR chip in the Bluebird, that it will make more options available
in the com options, that's how I was able to get my printer to work, so that may help in getting the SAS working in the BlueBird as well
